Zusammenfassung:	A light shielding plate for shielding part of light from a light emitting element to a projection lens is arranged between the light emitting element and the projection lens, and an opening penetrating the light shielding plate is formed in a required region of the light shielding plate. With this configuration, the drawing light distribution pattern can be formed as a light distribution pattern corresponding to the opening shape of the opening. In this configuration, the inner peripheral surface of the opening has such a surface shape that light emitted from the light emitting center of the light emitting element does not enter the projection lens. Thus, even if the plate thickness of the light shielding plate is increased, occurrence of color unevenness in an outline portion of the drawing light distribution pattern due to light reflection on the inner peripheral surface of the opening is effectively reduced.
